14 claims. (ci. esa-29) 'I'his invention relates to improvements insheet form holders for receiving and holding sheet forms interleavedwith carbon sheets and which are adapted to be fed through a printingmachine, such as a teletypewriter,

The primary object of the invention is to provide a plurality of sheetform holder units which may be normally arranged in stacked formation,one upon the other, but which may be slid relative to each other intooverlapping strip formation to facilitate the continuous'feeding of theunits through a 'printing machine, such as a teletypewter.

Another object of the invention is to provide a combined carbon sheetand sheet form holder in which the slidable holder units overlap eachother when in their extended position; that is, the lower end of oneunit overlies the top of the next adjacent unit. 'I'his feature.requires but a slight feeding movement of the form strip in ateletypewriter to bring the top of a sheet to be typed into typingposition after the completion of typing on the adjacent advanced sheet.This overlapping will not interfere with the space of a form sheet to betyped because such sheets are usually provided with a printed headingwhich in this instance is covered by the overlapping of the holderunits.

Another object of the invention is the provision of an extensible formand carbon sheet holder in which the units forming the holder may beindividually disconnected should it be desired for any reason toseparate one of the units from the other.

A further 'object is to provide a plurality of slidably connected holderunits which, when in their fully extended position, overlap each otherso that the bottom edge of one unit overlies the upper edge of the nextadjacent unit, and which not only produces a continuous feed strip. butalso serves to hold the collated form sheets in a. flattened conditionwithin the holder units.

which the collated sheets may be easily inserted or removed.

With these andl other objects in view, the invention resides in thenovel construction, combination and arrangement of the parts, the essen-5 tial features of which are hereinafter fully described, areparticularly'pointed out in the appended claims, and are illustrated inthe accom panying drawings in which:

Fig. 11 is a fragmentary perspective view illus- 30 trating the mannerin which the releasable tongue of one holder unit connects with theflexible strap of the next adjacent holder unit.

Referring to the drawings by reference characters, and more particularlyto the form of my 35 invention shown in Figs. 1 to 7, inclusive, thenumeral I0 designates one of the form holder units which comprises theflexible back piece or body I I which is substantially rectangular inconfiguration, and of a size to accommodate the size 40 of the formsheets to be held. The opposite side edges of the body II are foldedinwardly to provide parallel side flaps I2, the same being secured tothe body by lines of stitching I3. 'I'he stitching I3 is disposedinwardly of the inner 45 edges of the side flaps to enable the formsheets I and their interleaved carbon sheets to be inserted.Equidistantly spaced perforations I4 are 'provided in the aps I2 and inthe body II outside of the lines of stitching I3 for facilitating thefeed- 50 ing of the units I0 through a printing machine, such as ateletypewriter, whichemploys toothed wheels for accurately feeding theform strips through the machine.

A bottom end ap I5 is folded inwardly at one 55 end -of the body II andis secured at its ends by the lines of stitching I3 in order to providea pocket at the lower end of the body I I. The flap I5 is cut away asshown at for a purpose to be subsequently explained.

Extending transversely at the top end of the body II is a releasablefastening strap I1, one end being fixedly secured, such as by anadhesive or by stitching I3, to one of the side flaps I2 as at I3 whilethe opposite end of the strapl I1 is folded inwardly to provide a tab ortongue I! which is adapted to underlie one of the edges of the body IIas best seen in Fig. 4 of the draw-` straps 2I extend the length of thebody II. Due

to the fact that only their opposite ends are in secured engagement withthe body II, the major portion of the strap 2l is .left free of the bodyII. These straps 2I are provided as guide strips for a purpose now to beexplained.

In use, a plurality of the holder units I0 are adapted to be connectedand joined by threading, or passing, the flexible strap I1 of one unitI0 between the parallel straps 2I and the body II of the next adjacentunit I0. After the strap I1 has been so connected with the straps 2|,the free end of strap I1 (which has the tongue I9) is engaged with theadjacent edge of the body II by putting tongue I9 of the looped free endof the strap I1 into notch 20. When a plurality of these units II) areso connected (as is shown in Figs. 1 to 3, inclusive), a structure isprovided which permits the units I 0 to be slid longitudinally withrespect to each other. In other words, the units I0 may be slid intostacked formation, one upon the other (as shown in Fig. 3) and then bypulling outwardly upon the uppermost unit I0, it will slide to anextended position and will cause theother units I0 to be pulled fromtheir stacked formation. When the units III are fully extended, as shownin Figs. 1 and 2, the lower end of one unit I0 overlaps the upper end ofthe adjacent unit I0 thereby producing a continuous form strip.

Insertible into'each of the holder units is a combined form and carbonpack, as shown in Fig. 5 of the drawings, which consists of blank formsheets 22 interleaved with carbon sheets 23. The upper ends of thecarbon sheets are notched as at 24 while the lower ends are providedwith finger tabs, or extensions 45. The collated form pack is adapted tobe inserted into one of the holder units I 0 by sliding it through theopen top end of the unit I IJ. The sides of the pack are disposedbeneath the inwardly extending side aps I2 while the bottom, or lowerend, of the pack is slid beneath the bottom end iiap I5 and has theextension tabs 45 exposed through the cut away portion I6.

When it is desired to disassociate the form sheets 22 from the carbonsheets 23 after they are positioned in a holder unit I0, such as afterthey have been typed upon, it is only necessary for an operator to graspthe tabs 45 with the fingers oi one hand and exert a pull with the ngersof the other hand upon that portion of the form sheets 22 which overliesthe notches 2l in the carbon sheets 23.

In the event that it should become necessary to separate one or anynumber of the holder units ID from a strip, it is only necessary torelease the fastening strap I1 and disconnect it from the straps 2I ofthe next adjacent unit I0.

In Figs. 8to 11, inclusive, I have illustrated a slightly modified formof my invention wherein each holder unit I0' is constructed of asubstantially rectangular back piece, or body, 25 of tough .flexiblematerial and is provided with spaced perforations 26 adjacent to theopposite side edges of the body 25. Secured on the front side of thebackingpiece, or body, 25 and disposed adjacent and parallel with theside edges thereof are flexible straps 21 which extend the full lengthof the body 25 and have their opposite ends flxedly secured thereto,such as by stitching 28. An inwardly extending flap 28 is provided atthe lower end of the body 25 and is fastened to the edge of the body 25,such as by stitching 29. The upper ends of the straps 21 have theirinner edges notched as at 30 to facilitate the insertion of a combinedcarbon and form pack 3l beneath the straps 21, while the lower ends ofthe pack 3| are inserted beneath the ap 28.

Secured to the back of the body 25 adjacent to its lower end by anysuitable means, such as by an adhesive or by stitching, are tongues 32,the free ends of which are adapted to be inserted through slits, orslots, 33 provided in the body 25. In this form of the invention, whenconnecting the holder units I0' together, the tongues 32 of one unit I0'are engaged with the straps 21 of the next adjacent unit I0 and arelocked by their insertion through the slots 33. The same result is thusobtained in this modification of the invention as that described inconnection with the preferred form of the invention.

It is to be understood that after a strip of these holder units I0 orID' has been passed through a printing machine, such as ateletypewriter, the

form and carbon sheets 22 and 23, or pack 3 I, are removed from theholder and the holder is relled with new form sheets interleaved withcarbon sheets. It is also to be understood that the form holders aredisposed in stacked formation and automatically slide to their extendedposition during the process of feeding the strip through the printingmachine. After passing through the printing machine, the form holdersagain assume a stacked position.

While I have shown and described what I deem to be the most desirableembodiments of my invention, various changes in construction may beresorted to, if desired, without departing from the spirit of theinvention which is to be limited only by the scope of the appendedclaims.
